    GlossaryGonadotropin-Releasing Hormone Antagonists

    medications that block hormone signals to reduce sex hormone production

    Gonadotropin-Releasing Hormone Antagonists (GnRH antagonists) are medications that block the action of GnRH, a hormone responsible for stimulating the release of other hormones like LH and FSH from the pituitary gland. By inhibiting this pathway, GnRH antagonists can reduce the production of sex hormones such as testosterone and estrogen, making them useful in treatments for conditions like prostate cancer, endometriosis, and certain fertility issues.

      community EMA is re-examining Winlevi (clascoterone at lower concentration)

      in Treatment  8 upvotes 11 months ago
      Clascoterone in Winlevi, a topical AR antagonist, is being re-examined due to concerns about HPA axis suppression in adolescents, but it's unlikely to be banned for adult use in androgenetic alopecia (AGA). The European Medicines Agency recommended refusing Winlevi for acne vulgaris, but this may not affect Breezula's approval for AGA.

      community Pyrilutamide ,the molecule’s true nature

      in Research  302 upvotes 1 year ago
      Pyrilutamide is a selective AR antagonist with a high binding affinity, making it effective in competing with DHT for androgen receptors. The 1% concentration is more effective than the 0.5%, but the latter may suffice for mild hair loss; the drug is considered a good option for those avoiding 5AR blockers due to side effects.

      community Low dose spiro with 5ARI inhibitor

      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 1 year ago
      FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.
